Key Concepts and Terminology:
1. Ratio scale: A measurement scale that has a meaningful zero point and is unbounded at the top. In the context of money, it refers to the scale of punitive damages, where the dollar amount represents the intention to punish.
2. Anchoring: The cognitive bias where individuals rely too heavily on an initial piece of information (the anchor) when making judgments or decisions. Anchors can significantly influence subsequent judgments, even if they are arbitrary or unrelated to the decision at hand.
3. Coherent arbitrariness: The term used to describe the persistent effect of a single anchor on subsequent judgments. It refers to the phenomenon where an initial arbitrary decision or anchor can shape and influence subsequent judgments, making them consistent with the initial anchor.
4. Affect heuristic: The cognitive bias where people rely on their emotions or feelings to make judgments or decisions. It suggests that individuals determine what they think about something by consulting their feelings, leading to biased evaluations based on personal preferences or emotional reactions.
5. Confirmation bias: The tendency to search for, interpret, and remember information in a way that confirms one’s preexisting beliefs or hypotheses. It can lead to the disregard of conflicting evidence and the overemphasis of information that supports one’s existing beliefs.
6. Excessive coherence: The tendency to form coherent impressions quickly and be slow to change them, even in the face of new or contradictory evidence. It refers to the resistance to updating or revising initial judgments or evaluations, leading to biased decision-making.
7. Halo effect: The cognitive bias where an overall positive impression or evaluation of a person or thing influences the perception of specific attributes or qualities associated with that person or thing. It can lead to the overvaluation of positive traits and the undervaluation of negative traits based on the initial impression.
8. Base rate: The percentage or frequency of a particular event or outcome in a given population or reference class. It is used as a starting point for evaluating the likelihood or probability of similar events or outcomes.
9. Reference class: A group of similar cases or events that are considered comparable enough to serve as a basis for making judgments or predictions. It is used to establish a relevant context or benchmark for evaluating probabilities or outcomes.
10. Independent assessments: The practice of conducting evaluations or judgments in a way that minimizes the influence or bias from other assessments or opinions. It involves assigning different analysts to different assessments and encouraging them to work independently to reduce the risk of undue influence or halo effects.
Case Studies or Examples:
The book “Noise: A Flaw in Human Judgment” provides several case studies and examples to illustrate the impact of noise on decision-making. These examples span different domains and highlight the consequences of noise in various contexts. Some notable case studies and examples include:
